Apple noob needs help: iPad OTG questions from an Android guy

ruouttaurmind thought this was worth mentioning said

I bought a "well loved" iPad 2, with the intention of using it to watch movies on an upcoming adventure. It's only a 16GB, and it's running iOS 9.3.1

Knowing in advance that 16GB won't accommodate many movies, I'm wondering about using a flash drive to store the movies and either watch them from the flash drive, or transfer movies from the flash drive to the iPad a few at a time as I watch them.

Can anyone who's actually done this before offer their experience? Is this even possible?
